Quick Overview

Murachs MySQL 3rd Edition Chapter 15 Exercise 1 and 2


1. Write a script that creates and calls a stored procedure named insert_glaccount. First, code a statement that creates a procedure that adds a new row to the General_Ledger_Accounts table in the AP schema. To do that this procedure should have two parameters, one for each of the two columns in this table. Then, code a CALL statement that tests this procedure. (Note that this table doesn't allow duplicate account descriptions.)


2. Write a script that creates and calls a stored function named test_glaccounts_description. First, create a function that tests whether an account description is already in the General_Ledger_Accounts table. To do that, this function should accept one parameter for the account description, and it should return a value of 1 if the account description is in the table or 0 if it isn't. (Note: If a SELECT statement doesn't return any data, it raises a NOT FOUND condition that your function can handle.)
